Bethenny Frankel Vacations in Saint-Tropez with Warren Lichtenstein

The billion-dollar question: Are they travel pals or is romance brewing for Bethenny Frankel?

Frankel was seen Thursday enjoying a holiday in Saint-Tropez with longtime confidant and hedge-fund mogul Warren Lichtenstein.

Frankel, 42, looked cool and chic on her trip in platforms, a short skirt and tank top. She walked side by side with Lichtenstein, a billionaire from New York, who is the chairman and CEO of Steel Partners Holdings L.P.
